ROBERT RANELS BOGGS, OF SPRING RUN, PENNSYLVANIA.

HUB.

SPECIFICATION forming part of Letters Patent No. 640,737, dated January9, 1900.

To all whom it may concern.-

Be it known that I, ROBERT RANELs Boees, a citizen of the United States,residing at Spring Run, in the county of Franklin and State ofPennsylvania, have invented certain new and useful Improvements in Hubs;and I do hereby declare the following to'be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to the construction of parts necessary to provide awheel designed more especially for carriages, wagons, and other similarvehicles, the object being to pro- Vide means for compensating for theshrinkage of the wooden parts of the wheel, and thereby restore fromtime to time the desired tension or homogeneity of the parts.

By reference to the following specification and the accompanyingdrawings it will be seen that this result is easily accomplished withoutthe necessity of separating the several parts composing the completewheel 'or without shrinking or resetting the tire, as is now commonpractice.

In the accompanying drawings, Figure l is a central longitudinal sectionof my improved hub. Fig. 2 is a transverse section of Fig. 1, taken on aline central to the spokes. Fig. 3 is an edge view of one of the spokes.Fig. 4 shows a modified construction of the parts employed to hold thespokes in position, while Figs. 5 and 6 show the complete hub asconstructed in Figs. 1 and 2 disassembled or slightly separated fromeach other.

Referring to the several details of my invention and the accessoriesrequired to illustrate the use thereof by numerals, 1 is the axle of thevehicle, which may be constructed substantially in the usual manner,except that I prefer to provide the integrally-extending flange 2, anddesigned to fit upon the usual spindle 3, formed on the axle 1, is thehub proper, which consists of the inwardlyextending sleeve 4 and theintegrally-formed outwardly-extending sleeve 5, the latter beingexteriorly threaded for a purpose which will be hereinafter specified.Integrally formed with said sleeves is the radial flange 6, soconstructed that the outer edge thereof will carry or be provided with aseries of spokeretaining sections 7, designed to form parti- Applicationfiled December 21, 1898.

tions between the spokes, and thereby hold them in their respectivepositions. A removable flange or washer 8 is provided in order to holdthe spokes in place between the sections 7 and to reliably house andprotect them from the grit, dust, or'the like, said flange or washer 8being provided with a central aperture formed by the outwardly-extendingrib to provide a seating for the bushings 12 and 13, said seats beingpreferably provided by reaming out or recessing each end and thread ingthe same, the bushing 12 being preferably extended sufficiently to lieunder the flange 2 in order to insure against the introduction of grit,inasmuch as the line of travel for the grit is increased or extended.

The usual retaining-nut 14 is provided for the spindle, while the sleeve10 is preferably extended sufficiently to entirely inclose said nut,thereby more effectively protecting the bearing. Designed to cooperatewith the beveled face 11 of the sleeve 10 are the several ends of thespokes, each of which is preferably cut away or beveled upon one side toprovide the inclined face 15, and it is obvious that byrotating thesleeve 10 in the proper direction the beveled face 11 thereon willengage the ends of all the spokes and force them radially outward,thereby resulting in bringing them all tightly to bear against the fellyor rim of the wheel, thus resulting in giving to the parts the desiredtension requisite in a perfect wheel. It is also clear that a reverserotation of the wheel 10 will withdraw the beveled face 11 fromengagement with the several spokes, and thereby permit said spokes toextend inward sufficiently to readily disengage the tire from the rim ofthe wheel for the purpose of renewal or repair. The flange or washer 8may be held in its operative position in any preferred way, as by aseries of bolts 16, preferably having an inclined head 17 in case theradial flange 6 is provided, as in Fig. 1, with an inclined face, saidinclined head being designed, asis obvious, to bring the parts closelytogether in aneat and finished manner, said bolts being retained inposition by any suitable means, as by the locking-nuts 18.

If deemed desirable, a notch or recess 19 may be provided upon the sideof each of the spokes, as in case when the bolts 16 are of a largersize. By reference to Fig. 2 it will be seen that each alternate section7 is of less extent than the other sections, the object in reducing thereach of each alternate section being for the purpose of providing roomfor the accommodation of the lockingbolts 16.

In Fig. 2 l have shown the several spokes truly alined at their innerends and in close contact with the tapered end 11 of the sleeve 10, andit is clear that by this arrangement all the spokes will besimultaneously forced outward, thus distributing the pressure brought tobear upon the rim of the wheel equally throughout the circumferencethereof.

The sleeve 10 is preferably provided'with an octagonal face 20 or withother suitable wrench-cooperating surface, thus rendering it unnecessaryto employ a pipe-wrench to adjust the sleeve.

In Fig. 4 I- have shown another form of construction to be employed forthe several secj encircling bushing threaded on its exterior, a hubhaving an outwardly-extending sleeve threaded on its exterior and on itsinterior, the latter engaging said bushing, an outer sleeve 1O threadedon its interior and mesh- ,ing with sleeve 5, and an outer removableflange 8 encircling the sleeve 10, all arranged tions 7, as it will beseen by reference to Fig. .5 that said sections are provided withparallel sides, thus making them of equal size or extent throughout,while in Fig. i said sections are replaced by a series of taperingsections or partitions 21, the object of which is to compensate for anyshrinkage of the spokes, as it is clear that should any shrinkage takeplace all that is necessary in order to restore a perfect fit of theparts is to draw the flange 8 toward the free ends of the sections 21 bysuitable locking-bolts. The other parts ill ustrated in Fig. 4 aresubstantially of the same construction shown in Fig. 1, and they aretherefore designated by the same referencenumerals.

The several parts of my improved hub may be cheaply constructed andreadily assembled in the respective operative positions, and it is clearthat after the spokes have been properly mounted between the sectionsibr21, as the case may be, and the tire of the wheel secured in positionthe wheel may be given the desired tension or a proper dish may beimparted thereto by simply forcing the tapered end 11 inward by a properrotation of the sleeve 10. After the wheel has been in use sufficientlyto thoroughly season and shrink the wooden parts forming the same theoriginal tension or dish may be quickly restored by forcing the sleeveinward to the desired extent as before. It is clear that a suitablewasher may be placed between the flange 8 and the ends of the sections 7or 21, which may be subsequently removed, as by so doing provision willbe made for shrinkage of the spokes when the flange 8 will be forceddirectly in contact with the ends of said sections by means of thelocking-bolts 16. It is also clear that, if deemed a preferableconstruction, the flange 9 may be threaded upon the sleeve 10, thusenabling the several locking-bolts 16 to be entirely dispensed with, asby rotating the flange 9 upon said sleeve the flange 8 will be broughtsnugly against the free ends of the sections 7.

While I have described the preferred con struction' deemed desirable tomaterialize my invention, I desire to comprehend in this application anysubstantial equivalent thereof.

Having thus fully described my invention, :what I claim as new, anddesire to secure by Letters Patent, is

2. A hub having a central portion provided with spokes and having rightand left exteriorly-threaded' bushings, also an inward sleeve threadedon its interior meshing with the left bushing and further an outwardsleeve threaded on its exterior and on its i nte- ROBERT RANELS BOGGS.
